MobPushAuth

This is a demo Phoenix app that shows how to use Web Push notification to authenticate users.

The flow involves 2 steps:

1. Registration: on a computer, a user opens a QR code on his/her phone. The user accepts push notifications to be sent on his/her phone
2. Authentication: on a computer, the user enters his/her login. A web push notification is sent to his/her phone with a link. The link opens a web page asking for authentication confirmation. Upon acceptance, the user is authenticated on the computer
